Application filed June 8,1907- Serial No. 377,971-

To all whom it may concern:

Be it known that I, JAMES E. SAoKErT, citizen of the United States, residing at Sparrow Bush, in the county of Orange and State of New York, have invented new and useful Improvements in Roller-Bearings, of which the following is a specificatiom f? My present invention relates to roller bearings; and it contemplates the provision of a roller bearing designed for use to advantage in vehicle wheels, loose pulleys and the like, and embodying such a construction that friction is reduced to a minimum without the use of lubricant, and dust is eflectually excluded from the anti-friction parts.

The invention will be fully understood from the following description and claims When the same are read in connection with the drawings, accompanying and forming part'of this specification, in which:

Figure 1 is a view, partly in longitudinal section and partly in elevation, illustrating a Wheel hub embodying the construction constituting the present and preferred embodiment of my invention. Fig. 2 is a transverse section taken in the plane indicated by the line 22 of Fig. 1. Fig. 3 is-a transverse section taken in the plane indicated by the line 33 of Fig. 1, and: Figs'.4, 5 and 6 are elevations illustrating the three kinds of antifriction rollers employed in my novel roller bearing.

1 the dust-band' and Similar letters designate corresponding parts in all of the views of the drawings, referring to which:

A is a shaft or axle, and B is the casing of my improvements, which is illustrated as a wheel hub. The said casing B is shown as provided with spoke sockets C. In its ends the-said casing B is provided with inner and outer smooth-bores D, D, Fig. 1,- and at the inner ends of said bores it has annular, inwardly-directed flanges E, for a purpose presently set forth.

F is a dust-band snugly arranged in the inner bore D.

G is a gasket seated in a groove a in the inner ed e of the band Fand snugly receivin the s aft or axle A.

I, J and K are bearing-rings, preferably of steel, fitted close in the smooth bore D and between the inner flan 'e E of easing B and L are headed bolts extending through the dust-band F- and the 4 65 bearing-rings H, I, J and K, and threaded into the said inner flange E of easing B. Byvirtue of this construction it will be seen that subsequent to the removal of the bolts L the dust-band F and the several bearingrings mentioned may be readily removed from the casing B and replaced with new parts, and this without the employment of skilled labor. The inside opposed portions of the bearing-rings H and I are shaped to form an annular groove 6 of V-shape in crosssection, and the inside opposed portions of the rings J andK are shaped to form a similar groove 0,- while the inside opposed portions of the rings. I and J arerabbeted and toothed as indicated by d.

M is a sleeve fixed on the shaft or axle A through the medium of a set-screw N and having a V-shaped circumferential groove 6 in vertical alinement with the before-men tioned groove 6, and also having a toothed rabbet or recess G(Kat its outer end.

P is a sleeve through the medium of a set screw R and having a V-shaped, circumferential grooveginvertical alinement with the before-mentioned groove '0 andalso having a toothed rabbet or recess h at its inner end, and S S ed on the shaft or axle A are anti-friction rollers, of which six are preferably employed, interposed between the sleeves M P and the series of bearing-rings H, I, J and K. The rollers Srespect'ively comprise end portions 8 having perimeters of V- shape in cross-section and adapted to movebetween the V-shaped grooves in the, bearing-ringsand the similar grooves in the sleeves, and a middle spur-gear portion 3' ar- 1 ranged to move in the rabbeted. and toothed portions of the bearing-rings and sleeves. It will thus be seen that'the rollers S are all retained in their proper relative positions, and that they are com elled to travel with the bearing-rings and t e casing B with the re- I sult that friction incident to rotation of the casing B is reduced to a minimum.

On the inner ends or bottoms of the spoke sockets C shoulders or abutments k are pro vided, and against said shoulders is arranged the inner of four bearing-rings, preferably of steel. The said bearing-rings are lettered T, U, V and W and are shaped as shown in cross-section; also, the two outer bearingrings V- and Wei the series are flanged and detachably connected through bolts X with the outer walls of the spoke sockets C, this in order that any bearing-ring may be readily' on the shaft or axle A and having smooth,

circumferential grooves m and also having a toothed circumferential groove n; and A A are anti-friction rollers of which eight are ing-rings and threaded into t preferably employed between the bearingrings T, U, V, W and the sleeve Y. ,The

said rollers A respectively comprise end portions 7) shaped to bear in the correspondingly-shaped grooves of the bearing-rings and sleeve Y, and a middle toothed ortion 1 adapted to engage the teeth 8 on t e bearing-ring U and the teeth in the groove n of the sleeve Y. In this arrangement the toothed portions of the rollers A retain the rollers in their proper relative positions and assure the rollers traveling with the casing B.

E and F are bearing-rings, preferably of steel, arranged in the outer smooth bore D of easing B. G is a dust-plate also arranged l in said bore D, and H H are headed bolts extending through said dustlate? and hearhe outer flange E of casing B. Thus it will be seen that when impaired, either of the bearing-rings E F may be readily removed and replaced with a new bearing ring.

H is a sleeve detachably secured through a set screw 1 on the shaft or axle A and having a toothed groove a" and a rabbeted oute; end I).

J is a sleeve detachably secured by a set screw K on the shaft or axle A and having a toothed groove 0 and a rabbeted inner end d, and L L are anti-friction rollers, of which eight are preferably employed, interposed between the bearing-rings E F and the sleeves H and J. have end toothed portions 0 to engage the toothed grooves of the sleeves H and J and the toothed portions a of the bearing-rings E and F, and an intermediate portion (1 having a perimeter of V-shape in cross-section adapted to move in the V-shaped groove formed by the rabbeted ends of the sleeves II and J and the rabbeted ends of the bearingrings E" and F. Thus the relative arrangement of the rollers L is preserved and said rollers are compelled to travel with the casing B to conduce to the friction-eliminating qualities of the bearing.

It will be gathered from the foregoing that my level roller-bearing is efficient in operation without the use of lubricant, and that it is dust-proof and simple and inex ensive in construction and is well adapte to withstand the hard usage to which roller-bearings are ordinarily subjected.

The construction herein shown and described constitutes the preferred embodiment of my invention, but it is obvious that in practice various changes in the form, construction and relative arrangement-of parts The said rollers L each may be made without involving de arture from the scope of my invention as de ed in the claims appended.
